ABSTRACT

A refrigerator comprises a shell body ( 1 ) divided into a refrigerating chamber ( 2 ) and a freezing chamber ( 3 ), and a door body ( 20 ) selectively opening and closing the refrigerating chamber ( 2 ) and the freezing chamber ( 3 ), and further comprises an ice-making chamber ( 21 ) and movable supporting mechanisms ( 213, 214 ) connecting the ice-making chamber ( 21 ) and the inner wall of the shell body ( 1 ).

FIELD OF THE INVENTION

The present invention relates to a refrigerating equipment field, and in particular to a refrigerator.

BACKGROUND OF THE INVENTION

Following people's demands, the functions of refrigerator get more diversity gradually, among which the function of ice-making has increasingly become a factor people consider when selecting a refrigerator.

The equipment that ice-making relies on is an ice maker. The positioning of the ice makers in the existing refrigerators generally comprises two modes as follows.

First one is, the ice maker is placed in the refrigerating chamber. In this solution, as the ice maker is fixed in the refrigerating chamber, the space of the refrigerating chamber behind the ice maker can hardly be effectively used. Even if it is barely used, it is quite inconvenient for a user to take out and place articles behind the ice maker.

Second one is, the ice maker is placed in the door body. In this solution, as the ice maker is integrated into the door body, the weight of the door body per se is thus increased, which thus increases the bearing of the joint of the door body and reduces its service life.

Moreover, in both of the solutions above, when a user opens the door body to take out and place articles on the door body, the cold quantity in the refrigerating chamber will be lost and a lot of energy will be consumed.

SUMMARY OF THE INVENTION

The technical problem to be addressed by the present invention is to provide a refrigerator with an ice maker, capable of utilizing the space in the refrigerator effectively and facilitating placing and taking out articles.

In order to address the above technical problem, the present invention provides a refrigerator, comprising a shell body divided into a refrigerating chamber and a freezing chamber, and a door body selectively opening and closing the refrigerating chamber and the freezing chamber, and further comprising an ice-making chamber and movable supporting mechanisms connecting the ice-making chamber and the inner wall of the shell body.

DETAILED DESCRIPTION OF EMBODIMENTS

The present invention will be illustrated in detail with reference to the drawings.

Firstly, the principle of the present invention is illustrated briefly. In the present invention, the ice-making chamber and the shell body are designed to be movably connected in order to avoid that the space behind the ice-making chamber can not be utilized and inconvenience of storing and taking out articles in use. When articles need to be stored and taken out, the rear space can be exposed merely by rotating the ice-making chamber out from the refrigerating chamber/freezing chamber, which facilitates storing and taking out articles and makes the space sufficiently used.

Moreover, the weight of the door body per se is reduced and the service life of the joint between the door body and the shell body is prolonged as the ice-making chamber is separate from the door body. And such separation arrangement also effectively decreases the cold quantity loss of the refrigerating chamber when the door body is open to take out or place articles.
